Oxidative stress: oxidants and antioxidants [PDF]
Experimental Physiology, 1997 An imbalance between oxidants and antioxidants in favour of the oxidants, potentially leading to damage, is termed ‘oxidative stress’. Oxidants are formed as a normal product of aerobic metabolism but can be produced at elevated rates under pathophysiological conditions. Antioxidant defense involves several strategies, both enzymatic and non‐enzymatic.

Iodine-catalyzed diazo activation to access radical reactivity
Nature Communications, 2018 Radical reactivity of diazo compounds, useful organic building blocks, is yet underexplored. Here, the authors report an iodine-catalyzed radical activation of diazo compounds affording a variety of substituted cyclopropanes, pyrroles and epoxides under ...

Chemical Bonding Analysis on Amphoteric Hydrogen - Alkaline Earth Ammine Borohydrides
, 2017 Usually the ions in solid are in the positive oxidation states or in the negative oxidation state depending upon the chemical environment. It is highly unusual for an ion having both positive as well as negative oxidation state in a particular compound ...

Photo-Fenton Degradation of Pentachlorophenol: Competition between Additives and Photolysis
Nanomaterials, 2019 In the present work, the photo-Fenton degradation of pentachlorophenol (PCP, 1 mg/L) has been studied under simulated and natural solar irradiation; moreover, the effect on the process efficiency of urban waste-derived soluble bio-based substances (SBO),

Paraoxonase Role in Human Neurodegenerative Diseases
Antioxidants, 2020 The human body has biological redox systems capable of preventing or mitigating the damage caused by increased oxidative stress throughout life. One of them are the paraoxonase (PON) enzymes.

Influence of oxidized oils on digestibility of caseins in O/W emulsions [PDF]
, 2018 The impact of lipid oxidation on protein modifications in emulsions and the consequences on protein digestibility remains unclear. In this study, this impact is evaluated in casein (6 mg mL(-1)) based emulsions containing oxidized soybean or fish oil (3%)

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Oxidative Shielding or Oxidative Stress? [PDF]
The Journal of Pharmacology and Experimental Therapeutics, 2012 In this review I report evidence that the mainstream field of oxidative damage biology has been running fast in the wrong direction for more than 50 years. Reactive oxygen species (ROS) and chronic oxidative changes in membrane lipids and proteins found in many chronic diseases are not the result of accidental damage.
